I bought this computer a few months ago, and have been gradually working toward a full repair. Unfortunately, this computer was the victim of a Maxell battery explosion (didn't know it was a common issue when I bought it). Regardless, I've made a lot of progress from where things started. Here is a list of what I've done:
My analog board has not been recapped, but it successfully powers a Classic II board, HD, and floppy without issue, so I am thinking that's less of a suspect. Rail voltages are 11.49, 4.75, and -11.88 for the +12, 5, and -12V systems. If I am wrong in thinking that the voltages are enough then please tell me otherwise. Any advice on things to check next would be appreciated!
- Cleaned battery area and removed all acid/corrosion
- Visually inspected and repaired damaged vias with magnet wire
- Replaced all electrolytic capacitors and confirmed continuity of all nearby vias
- Checked continuity of almost all traces going to and from 68000 CPU
- Cleaned with IPA to remove any traces of flux or debris
